The present invention relates to new oligonucleotide arrays and methods of using oligonucleotide arrays. Binary oligonucleotide arrays, having binary oligonucleotides characterized by a constant nucleotide sequence adjacent to a variable nucleotide sequence, are used for sorting and surveying nucleic acid strands. Oligonucleotide arrays are used for sorting mixtures of nucleic acid strands, making immobilized partial copies of nucleic strands, ligating strands, or introducing site directed mutations into strands. Information is obtained for determining the sequence of a nucleic acid strand, alone or in a mixture, by generating partials of the strand and, for groups of partials having the same terminal variable oligonucleotide, separately determining the presence and sequence of all variable oligonucleotides. Arrays are also used to order previously sequenced nucleic acid fragments and to allocate ordered allelic fragments to chromosomal linkage groups. |
